As one of the youngest members of S.H.I.E.L.D., Jemma Simmons (Elizabeth Henstridge) may be a little green in the field, but she's certainly one of the brightest minds on ABC's new drama Marvel's Agents of S.H.I.E.L.D. Combined with fellow agent Leo Fitz (Iain De Caestecker), the duo is an unstoppable scientific force that complements each other like a married couple, according to Henstridge. The 26-year-old actress, whose credits included the British soap Hollyoaks before joining Joss Whedon's world of weird, dissects her new character with TVGuide.com and answers some of our burning questions, including whether there's more than meets the eye to Fitz and Simmons' relationship. Get the scoop:

Question: So we had the first cancellation of the season with Lucky 7 after two showings. There are no tears from me as I never watched it. My question is: On what planet did anyone ever perceive this show's premise to be interesting or sustainable? Out of the hundreds of pilots, it is sometimes hard to believe someone at ABC thought this was one of the best. What do you think is next? — Rob

Matt Roush: Next for ABC, or next in the long annals of "what were they thinking" pilots? (That sound you hear is ABC kicking itself for not keeping Body of Proof around as a back-up, because for the time being, Scandal repeats will be airing in place of the unlucky 7.) To be fair, Lucky was based on a more successful British series, The Syndicate, but something clearly got lost in translation. (Same thing must have happened regarding ABC's equally mediocre Betrayal, based on a Dutch series and adapted by the same exec producer, who's batting 0 for 2 right now.) Your point about the sustainability of a pilot's premise is a good one, and comes up frequently when analyzing the failure of shows as disparate as last season's Last Resort and (though it may be premature) this season's Hostages — more on that one later. But from the moment many of us saw clips of Lucky 7 at last spring's upfront presentation, it felt like nothing we could imagine almost anyone would want to see. And we were right.

This week, ABC launched its online companion series to Marvel's Agents of S.H.I.E.L.D., "Agents of S.H.I.E.L.D. Declassified," in conjunction with the series premiere. An Internet genius decided to combine Breaking Bad with the Seinfeldtheme music and laugh track and turn AMC's dark drama into a quirky comedy, whileDean Norris gave us a hint at what might be next for Hank Schraeder. In other AMC-related content, College Humor hilariously pondered why no one's watching Low Winter Sun.And, Homelandfans who are gearing up for the Season 3 premiere on Sunday can check out the Abu Nazir Acting School, as well as Homeland: The Musical.

Meet the man most directly responsible for Marvel's super-spy organization and for making Nick Fury the eye-patched badass he is today -- and he'll be giving us his thoughts on "Agents of SHIELD" every week.

Maurissa Tancharoen and Jed Whedon talk with THR about "The Avengers" follow-up, coping with the pressure of being Marvel's first scripted effort and how they'll court families as ABC looks to the comics-themed drama to rebuild Tuesdays.

When it comes to heavy lifting, Marvel's Agents of S.H.I.E.L.D. is being asked to flex more than its share of muscle. Leading off an entire night of new ABC programming (always a risk, especially in these fragmented times), taking on TV's top-rated drama (NCIS), satisfying the expectations of Marvel Comics fans and Joss Whedon's considerable cult following, that's a lot for any spin-off to live up to, even with source material like The Avengers.

A Norse God. A flying billionaire in an iron suit. A man frozen in time. A giant green rage monster. These are just a few of the characters that Marvel has somehow made relatable throughout its films. But now, in their quest to bring that same magic to TV, ABC will attempt to get the fanboys, fangirls and the uninitiated to tune in for Marvel's Agents of S.H.I.E.L.D.

On the TV show, which airs Tuesday at 8/7c on ABC, Agent Coulson (Clark Gregg) assembles a select group of agents to form the worldwide law-enforcement organization known as S.H.I.E.L.D. — Strategic Homeland Intervention Enforcement and Logistics Division — which investigates strange and unknown occurrences around the globe. The team includes Agents Melinda May (Ming-Na Wen) and Grant Ward (Brett Dalton), scientists Fitz (Ian De Caestrecker) and Simmons (Elizabeth Henstridge), as well as hacker-anarchist Skye (Chloe Bennet), who adamantly works against the S.H.I.E.L.D. team until she discovers their true nature.

So how will the world of S.H.I.E.L.D. be approachable for both diehard comic book fans and new viewers alike?

After The Avengers pulled in $1.5 billion globally and other Marvel blockbusters like Thor, Captain America: The First Avengerand the Iron Man franchise succeeded at the box office, ABC's collaboration with Marvel appeared to be a sure thing. Add to that that S.H.I.E.L.D. marks the television return of Buffy the Vampire Slayercreator and Avengers director Joss Whedon, who brings with him even bigger expectations for the new series.

On S.H.I.E.L.D., which is an offshoot of The Avengersfilm franchise, Agent Coulson...

Question: My question is about the new Joss Whedon show that has one of the most convoluted names I've ever heard: Marvel's Agents of S.H.I.E.L.D. I am a Whedon fan to the max, having watched every episode of every TV (and Internet) show he has ever done, and enjoyed them thoroughly. I am not, however, a moviegoer nor a comic book reader. I cannot remember the last theatrical production I've seen, and the only comics I read are the Buffy/Angel follow-ups. And that leaves me concerned about S.H.I.E.L.D. Every article I read, and even the just-released preview, mentions events that happened/people who existed in one or more theatrical movies, and many articles mention future movies that will tie into the events on the show. Since I never watched those movies — and most likely won't watch the future movies — am I going to be totally lost when the television show premieres?
